So separate enclosures for the different drivers is a good idea? Is that the reason why subs or woofer columns are separate from the mid panel or drivers and the line of tweeters? I had 123s 15+ years ago. They were a nightmare. I did everything GR said to do.. They got better but they were horrible. It took a basketball court to make them sort of work. 123s made you want to put headphones on..
The owner Danny didn't like them either. His OB design is an acquired taste. They are the best I've ever heard though. I'm no expert but "Toe in" or "OUT" is pretty important.
A lot of bass columns are toed OUT while the mids and highs are toed IN. It's always "the room" anyways and what you like. Bright is usually a room issue. The lack of mids? On and off axis is important if your dancing? I sit when I listen, so I adjust accordingly. When many people are listening I toe my Hybrid LS out. They aren't glued to the floor. :-) 1/4" difference in tow or tip helps with "Bright" too.
The answer to the question is "it just depends on what you like". Getting speakers away from walls is hard for some people to learn too. Treat the room like it's part of the speaker and you'll be fine..
